Notes:
1) Glycerine (07) is not available for vacuum & compound pressure measurement
ranges or autoclave design. Consult factory for exceptions.
2) List options in alphabetical order at the end of the conguration code.
3) All product under this model series is provided with calibration protocol, electropolished nish, and material based information report as standard.
4) Autoclave design requires Polysulfone window (WPS) and dry gauge case (932.25).
